mpl::transform_view takes an MPL lambda expression rather than a 
function object,
because it operates on types, not objects.  (most MPL constructs take lambda
expressions--mpl::for_each is a special case)

#include <boost/mpl/times.hpp>
...
typedef myfun<mpl::times<mpl::_1, mpl::_1>,numbers>::type newnum;
